Technical Field

[0001] This utility model belongs to the field of equipment for road and bridge construction, and in particular, it is a concrete pouring equipment for road and bridge construction. Background Technology

[0002] During the concrete construction of the bridge deck, concrete mixer trucks transported concrete to the area under the bridge via a temporary road. The concrete was then placed into hoppers, which were then lifted onto the bridge by a truck crane for pouring. This method resulted in a slow pouring speed. The truck crane needed to be moved after each span of the bridge deck was poured, significantly reducing construction efficiency. Furthermore, the crane operator had to manually direct the crane from under the bridge to move the hopper along the designated direction, creating blind spots and posing certain safety risks. After the concrete was poured using the hoppers, manual vibration and leveling were required, further reducing work efficiency. Utility Model Content

[0019] The working principle of this utility model is as follows:

[0020] When using this device, it is hoisted onto the bridge deck to be poured using a truck crane. The mixed concrete is then poured into hopper 4. Hoist 4 is then lifted by the truck crane and moved above the truck body 1-1. Hoist 4 is then lowered, passing between the rotating rollers 2-4 of the two support devices 2. As hopper 4 moves downwards, the rotating rollers 2-4 press against the outer wall of hopper 4 and expand along the outer wall until hopper 4 is placed in the hopper trough 1-1. Inside 2, the rotating roller 2-4 moves along the outer wall of the hopper 4, thereby causing the support arm 2-3 to rotate. Simultaneously, the coil spring 2-2 is compressed. Through the reaction force of the coil spring 2-2, the rotating roller 2-4 is pressed against the outer wall of the hopper 4, thus supporting the hopper 4 and increasing its stability. Then, the truck crane is separated from the hopper 4, and the discharge port of the hopper 4 is opened, allowing the concrete inside the hopper 4 to slide out, completing the pouring process. At the same time, the truck body 1-1 is pulled along the bridge structure to be poured. The concrete pouring process is completed simultaneously. Vibration motor 1-4 is energized to drive the arc-shaped plate 1-5 to vibrate. The vibration of the arc-shaped plate 1-5 is transmitted to the discharge port of hopper 4, allowing the concrete to slide out through the discharge port. The vibration prevents the concrete from getting stuck in the discharge port of hopper 4. Simultaneously, the vibration is transmitted through the discharge port of hopper 4 to the wall of hopper 4, shaking off any concrete adhering to the inner wall and preventing concrete from sticking to the wall. Energizing electric telescopic rod 3-2 moves the support plate 3-3 downwards, causing multiple scrapers 3-4 to press against the surface of the poured concrete. Then, energizing electric telescopic rod 3-5 moves the vibrator 3-6 downwards to below the poured concrete layer. Energizing the vibrator 3-6 vibrates the poured concrete, reducing air bubbles and increasing the density of the concrete, preventing hollow areas. As the vehicle body 1-1 moves, multiple scrapers 3-4 smooth the concrete surface, further increasing the efficiency of the pouring process.
